This invention relates to an improved window screen device forautomobile windows provided with vertically slidable window glasses.

` It is an object of this invention to provide an improved window screenand actuating means therefore of the kind to be more particularlydescribed hereinafter, which is mounted for sliding movement in a windowframe alongside the Window glass therein so that both its operatingmechanism and that of the window glass may be contained in therestricted interior space available within `the door or body of anautomobile or the like.

Another object of this invention is to `provide a door for an automobilehaving a verticallysliding window glass, a vertically-sliding screen,

and separate actuating means for the window glass and screen soconstructed anduarranged that either the window glass or screen may beraised or lowered, independently of each other, handle means beingdisposed on the inboard side of the door so as to be readily reached byan operator within the vehicle for operating the window glass andscreen.

With the above and other objects in View, my invention consists in thearrangement, combination and details of construction disclosed in thedrawings and specification, and then more particularly pointed out inthe appended claims.

In the drawings:

Figure 1 is a side elevation, partly broken away and partly in section,of the inboard `side of an automobile door having incorporated thereinwindow and screen-actuating means constructed according to an embodimentof my invention;

Figure 2 is a vertical, transverse section taken on the line 2--2 ofFigure 1;

Figure 3 is a vertical, longitudinal section taken on the line 3-3 ofFigure 2.

Referring to the drawings, the numeral I designates generally anautomobile door having a vertically-slidable window glass II and avertically slidable window screen I 2 adapted to be optionallypositioned in the opening of the window frame I4. Separate operatingmeans are provided for the window glass I I and for the screen I2 forindependently sliding the window glass I I Joiind the screen I2 toraised and lowered posions.

'Ihe door I0 is hollow and is formed in its upper part with an openwindow frame, the body of the door being provided internally with a pairof laterally adjacent guide channels I5 and I6 extending along oppositesides of the window frame I4 for guiding the window glass 1 Claim. (Cl.268-126) II and screen I2, respectively. The sill I1 of the door isformed with a longitudinal opening I8 through which both the windowglass I I and the screen I2 are movable upwardly from depressedpositions within the door IIJ below the sill I1.

The screen I2 is formed with a frame I9 having a reticulated centerportion 20, the frame I9 being slidable vertically in the guide channelI5, shown in the drawings as the innermost of the channels I5 and I6.The window II is formed with a peripheral frame 2| having a center solidtransparent body 22, and the window frame 2I is slidable vertically inthe guide channel I6, disposed outwardly of the guide channel I5 ole`scribed above. While the screen I2 `is` positioned inwardly of thewindow II in the drawings, it is to be understood that thescreen l2 maybe positioned outwardly of the Window II, the change being a matter ofchoice to be determined by the owner or manufacturer.

The frame I9 of the screen I2 is formed with a longitudinal, U-shapedchannel 24 fixed on the4 thereof vertical on the inner side of the frameI9, having one horizontal arm of the U-shaped channel secured to thelower surface of the lower longitudinal frame member. The bight portion25 of the channel or guide member 24 is formed with alongitudinally-extending horizontal slot 26 therein extendingsubstantially along the entire length of the guide member 24.

A lever 21 is pivotally mounted on `a bracket 28 fixed on the innerpanel 29 of the door. The lever 21 includes a gear segment 38 fixed onone end thereof, or preferably formed integrally therewith. The lever 21is pivotally mounted in the bracket 28 by a pivot pin 3| which extendsthrough the bracket 28 and the radial center of the segment 30. Thelever 21 also includes a forwardly-extending arm 32 iixed to or formedintegrally with one side of the segment gear 3|). The arm 32 isoutwardly offset intermediate the length thereof for the purpose to behereinafter described. The outer end of the arm 32 slidably engages theframe I9 by the engagement of the pin 34 fixed on the free end of thearm 32 and slidably engageable in the slot 21 formed in the guidechannel 24. A spring, as 35, is disposed about the pivot pin 3I forsubstantially balancing the weight of the screen I 2 in the door. Oneend of the spring 35 is fixed to the bracket 28, and the other end ofthe spring is fixed to the shaft or pivot pin 3l. Upon lowering of thescreen I2, the spring 35 will be slightly tensioned to assist in raisingthe frame and substantially' balancing the screen in the verticalmovement thereof.

A pinion gear 36 is fixed on the shaft 3'! which extends through theinner panel 29 of the door. The gear teeth of the pinion 36 engage withthe teeth of the segment gear 39 for rocking the lever 32 from a raisedto a lowered position. A handle or crankr38 is fixed to or formed on theinner end of the shaft 31 for rotating the'pinion gear 36 by theoperator within the vehicle.

The window II is raised and lowered by a mechanism substantially similarto the mecha-V nism described above for raising and lowering the windowscreen. A guide channel 49 similar to the guide channel 24 describedabove is xed on the` lower edge of the window framev 2l;VV The guidechannel 4I!l is U-shaped is cross-section, having one horizontal armthereof fixed to the-'lower frame member of the frame 2 I. The bightportion of the channel 46'is formed with alongitudinally-extendingislot'4I1 A lever,` asf42, is pive'otallymountedon a bracket 44 fixed `to` the outer sideof the innerv doorpanel- 29at the forward end thereof. The bracket 44issimilar to thebracket 28 describedV .above for the windowscreen-actuating` member,the' bracket 2 6V being; disposed adjacent the rearvertica-l edgey ofthedoor VI 0.: Both the bracket26 land vthe bracket 44= aredisposed atsubstantially the same horizontal level within the door.

Asthe Abracket 44 vis'disposed in substantially. thesame planefas the`bracket 28',the1leve1"42 y isformed for reaching acrossthe window screenframe I9l in the lowered position Aof .the screen, as; shown in Figures,liand" 2 of thel drawings, in; a mannertoraise andlower thewindow Il,ir: respective .of th'e relative positionrofthe screen IZI.

One end of the lever 42 is formed with an arcuate gear segment 45pivotally. mounted `in the L bracket'44 by a pivot pin `orshaft 46journaled in the bracket 44.V A spring, as48', is disposedabout theshaft46k inthe same mannerasfthe spring 35, describedlabove, one end of thespring 481being xedlto theibracket 441,-.theiother end of thespringbeing'xedron the shaft. 46.V A. pinion gear 49 is rotatably.`mounted in the..brael:etv 44v forengagementwith the gear teeth ontheseg'-vr ment 45 for rockingthelever 42on itspivot 46..Y Thegearf4 9isfixed onthe shaft 5B1which extends inwardly ofthe panel-2 9. of thedoor, andearries the crank 41 for operation of the `window by an`operator.

A substantially horizontal arm I yisfxedon theirgear segment .45 and.extends rearwardly of the ipivot`pin46 thereof. The arm .5I is formed.with a .short 'horizontally-extending arm 52 disiposed inwardlyofthewindow and screen frames. A U-shaped.:bridging member. 54 is fixed onthe rearmost end of the Ashort arm 52 and is disposed at substantiallyright angles thereto. arm, 55; ofthe :bridging member 54` is fixed ytoor formed integrally with .the Vfree end-` of the l short arm 52:andextendsdownwardly therefrom. The.l parallel 'side arm 56 of the bridgingmember'54 extends upwardly betweenl the. window II and screen I2'forengagement with the guide member 4I .xed on the:` lower side'of theframe V2.1 oftthe window. The side arms 55, and 56 of the U- shapedbridging'. member 54j are connected to- One side in substantially thesame horizontal plane as the short arm 52 described above. The arm 58 isxed to or formed integrally with the upper end of the side arm 56 of thebridging member 54. The free end of the arm 58 is slidably engaged inthe guide member 49 by connection thereto with a pin 59. The pin 59 isxed on the free end of the arm 58 and slidably engages in the slot 4I.

In Figures 1 and 2, the screen I2 is shown in itslowered position,while. the window I I is shown in its fully raised position; VIn Figure3, the positions of the window and screen are reversed, and the windowII is shown in its extreme lowered position,while:the screen I2 is shownin its extreme raised position. By the structure of the window 4andscreen-actuating means set forth herein, eitheruof fthe closures, thewindow or the screen, may be moved to any selected position,

' irrespective of the relative position of the overgether at their lowerendsby a4 horizontal bigh-trportion'5I. The side. arm `5I5-extendsYupwardly substantially the same length as the side arm 55, and: at the`extreme upper end vof the side arm 56 a rearwardly-extending shortarm-58 extends lying closure member. In other words, the windowandscreen mayfbe raised `both at thesame time; or-bothlowered atthesametimefand either one may besraised or lowered. to its-extremeforVintermediate, position, irrespective of the disposition andmovementofthe other closure member.-

Inthe use and operation Vofthe-'door I0 .de-

scribed above. whenit isfdesired to raise theV screen fromVits.concealed-position within the door, the crankr38 may be rotated forpivoting the Vlever-2`I upwardly. The lever 2'I engages `between the arm55fofthe. bridging member 54 and the screen, and offsetfintermediateYthe length.

thereof to provide a clearance between Vthe side arm` 55 andy the-screeninits loweredposition. Upon rotation of thew crank-.38, the lever 2Iwillbe rocked aboutthefpin- 3I from the downwardlyinclined position shown inFigure l to the upwardly-inclined position show-n in Figure 3.

For raisingandV lowering-.the window I I, the crank4'I maybe rotatedbythe operator. Rotation of the shaft 50 and the pinion 49 will effectrotation of lthe'segment gear- 45l about its pivot pin 46. The lever'42carried by the segment gear 45 Will be raised from itsdownwardly andrear- Wardly-inclined position 'v shown a in Figure 3 to its upwardly.-and rearwardly-inclined positionv If the screen I2 isin itsv shownin-Figure 1. lowermost position, when'the window- I I is raised,`

the bight portion 5l 'of the Vbridginggmember54- will be moved to aposition adjacent the-lower edge of the screen -frame I9 whenfthewindowI I is moved to its fully-raised position. When the window II is down,the bridging member 54 willV be disposedconsiderably below the :loweredges of both the window and the screen, so'thatfthere Y will be notinterference .between the window and the screen wheneitheraoneeis..raised whilethe4 other islowered.
